feat: Update ECMAscript 2015 => 2020
This enables the 2020 globals BigInt
and globalThis
(also
BigInt64Array
, BigUint64Array
, Atomics
and SharedArrayBuffer
).
The former two probably being the most useful.
We allow the espree parser to parse the latest ES versions, there should
be no harm in allowing these globals
.
